SCRAP BOOK AND LEAF UNIT THEREFOR Filed Nov. 1, 1926 Patented Nov. 26, 1929 A UNITED STATES FRED N. LANG, OF LOS ANGELES, CALIFORNIA SCRAPBOOK AND LEAF UNIT THEREFOR Application fil ed. November The forms in which the principles involved in my invention can be made and used are fully shown in the accompanying drawings, which, together with the following descri1o- 5 tion and claim, fully illustrate and explain what I claim as my invention.

The objects of my invention and manner of its construction and use are as follows.

To produce in the leaves of books and files, strong, flexible hinges whereby the leaves can be opened either backwards or forwards to a flat position without being bent or curved except at and along the line of the hinge; to strengthen the binding margin of the leaves so that they will stand the rough usage required of them when used in loose leaf binders; to thicken their binding margins in order to make the back or bound portion of the book or file as thick as the balance of the same when numerous clippings, photographs &c. have been fastened to the leaves; to bind two or more leaves together by means of a line of stitches running parallel with the edge of the binding margin and at a distance of about one inch distant therefrom, the stitched line acting as a hinge for the leaves, and also to hold in position the material used for thickening and strengthening the binding margin of the leaves; to hold the leaves of the twin leaf units so closely together at the line of stitches that when any two of them are opened a flat surface will be formed of twice the size of a single page upon which clippings of large size can be attached; to produce a strong and durable device for permanently holding the twin leaf units in book form in such a manner as to preserve the flat opening feature of the leaves along the stitched line and at the same time to furnish ample room between the twin leaf units to allow for the expansion of the leaves when numerous clippings 620. have been attached thereto.

In describing my invention in detail, reference is to be had to the accompanying drawings, in which Fig. 1 is a perspective view of a sheet of paper of double the size of the intended leaves which has been folded along its center.

1, 1926. Serial No." 145,476.

Fig. 2 is a perspective view of the sheet of paper mentioned in the preceding paragraph within the fold of which is shown a strip of cardboard, the purpose of which is to thicken and strengthen'the binding margin of the twin leaf unit,which is held in place by means of the stitched line.

Fig. 3 is a perspective view of a twin leaf unit the leaves of which have been opened was to produce a flat'page'of double the size of a single page.

Figure 4 is a perspective view of three of the twin leaf units assembled together in the position that they are held in a book or binder.

Figure 5 is a perspective view of three twin leaf units bound in a solid and permanent, binder.

Figure 6 is a perspective view of a slotted, wooden holder orbinder in which the-twin leaf units can be permanently held for use by means of an adhesive or by the use of nailsv driven through both holder and twin leaf units.

Similar letters refer to similar parts throughout the several views.

The leaves of the twin leaf units are represented by the letter a. The fold of the twin leaves is represented by the letter Z). The stitched line is represented by the letter 0. The thickening and strengthening filler is represented by the letter (Z. The holes punched in the margin of the twin leaf units are represented by the letter e. The slotted block binding back is represented by the letter 7. The slots in the binding block are represented by the letter g. The cover used in connection with the block binding back is represented by the letter h.

The twin or multiple leaf unit is formed by folding a sheet of paper of twice the size of the desired leaf along its center, within which other folders or single sheets may be added. When additional strength and thickness is desired along the binding margin of the twin leaf unit a filling of cardboard or other similar material and of the width of approximately one inch may be laid within the fold. A line of stitching is then sewed through all of the leaves on a line parallel with the fold of the leaves and about one through both thewoodand the leaves of the inch distance therefrom, thus retaining the filler in place.

The stitched line holds the leaves closely together and forms a hinge therefor whereby the leaves can be turned backward and forward and any two of them can be opened so as to forma surface double the size of a single,

leaf upon which clippings of large size can be placed.

When the twin leaf units are to be used in loose leaf books or binders provided with rings or posts, holes may be punched along the binding margin to fit the rings or posts of the books or binders in which they are used.

When the twin leaf unitsare to be bound in a permanent form, the binding block; 9 is provided, this block having slots into which the'unitsmay be inserted and held in place by;

of an adhesive or by nails driven units. hen the parts are thus assembled, the stitched. line forming. the hinge is spaced fromthewooden block and thus a free hinge action may take place without interference 1 with the block.

Having. described theobjects, manner of making and plan for us ng my invention, I

desire that Letters l atent be granted tome fe h lqw ng Q aim= A twin leaf unit for. scrap books adaptedto be inserted in a loose leaf or permanent binder, said unit eomprisinga folded sheet forming two leaves and a binding margin; the 1 leaves'being hinged to each other by a line.

of stitching spaced from the fold and; passingthrough both leaves, and a reinforcement for the binding margin extending from the t dt he i e of wh n FRED N. LANG.
